Illustration Friday 'Train'

Here's my entry for this week's Illustration Friday topic which is 'Train'. 

I used the opportunity this week to have a play with some new techniques in Illustrator that I've not tried before. I was going for an aged/printed sort of feel to the image. I'm not sure how successful it is though, what do you think? I did try lots of different colour combinations but this is the one I've gone with for now. I think it still needs work but for now I'm calling it done. I get the feeling I may revisit this at some point!
